Speaking in Washington at the annual dinner of the American Jewish Committee in May 2007, Argentina's then-senator Cristina Fernandez de Kirchner publicly reiterated her unwavering commitment to justice for the victims of the 1994 AMIA bombing, an Iran-sponsored terror attack against the Jewish cultural center in Buenos Aires that left 85 people dead and 229 wounded. But since becoming president, Kirchner has pursued an entirely different course. In January she signed a memorandum of understanding with Iran that will inevitably deny Iran's culpability.
For Iran, the motivation is clear. There is the immediate gain for most senior officials - including Ali Akbar Velayati, who was then foreign minister, and Mohsen Rezai, who was then the Revolutionary Guards' commander. Velayati was indicted by an Argentine judge for the attack and Interpol issued an arrest warrant for Rezai. Though neither succeeded in their bid for president in Iran's recent elections, they still maintain a high profile in Iran's power structure and a negotiated deal would rid them of this unpleasantness. More broadly, whitewashing Iran's involvement would give Tehran - a primary sponsor of terrorism across the globe - a dubious but technically clean bill of health that would further facilitate Iran's entrée in the region.
Argentina is also an important strategic addition to Iran's Latin America policy.
Iran's booming relations with the Bolivarian republics - Bolivia, Ecuador and Venezuela - are well documented. Since 2005, Iran's outgoing president, Mahmoud Ahmadinejad, visited Latin America at least once a year and opened new embassies across the continent - including in Bolivia, which appears to be the gateway to Latin America for Iranian spies, with reportedly 145 Iranian accredited diplomats.
All these countries offer Iran opportunities for political influence - they provide sympathetic votes in international forums - and an array of instruments to evade international sanctions. Iran, in turn, uses its soft power to help its Latin American partners - mostly developing countries and members of the non-aligned movement - to develop infrastructure, which brings hard currency to Iran's sanctions-battered financial system. Establishing cultural centers and mosques is also buying Iran influence among the small but influential population of Muslim immigrants and their descendants.
None of this, however, matches the potential of renewed friendship with Argentina - as evidenced by the fact that Iran's bilateral trade with the Bolivarian republics is almost non-existent; by contrast, 96 percent of its trade is with Argentina and Brazil.
Argentina and Brazil are in truth Latin America's regional powers. Since Brazil's former president Ignazio Lula de Silva left office, bilateral relations between Tehran and Brazil have significantly cooled, with Lula's successor, Dilma Vana Rousseff, distancing herself from president Ahmadinejad both in word and deed.
